The aim of this case study was to quantify the magnitude of internal load, acute/chronic workload ratio (ACWR), well-being perception, and heart rate variability (HRV) following 38 weeks of functional-fitness training in a female elite athlete. The internal load was obtained with session rating perceived exertion (session-RPE) while the ACWR was calculated by dividing the acute workload by the chronic workload (four-week average). Furthermore, HRV measurements were analyzed via a commercially available smartphone (HRV4training) each morning upon waking whilst in a supine position. The magnitude of internal load was: the weekly mean total during the 38 weeks was 2092 ± 861 arbitrary units (AU); during the preparation for the Open 2018 was 1973 ± 711 AU; during the Open 2018 it was 1686 ± 412 AU; and during the preparation for the Regionals was 3174 ± 595 AU. The mean ACWR was 1.1 ± 0.5 and 50% of the weeks were outside of the 'safe zone'. The well-being during the 38 weeks of training was 19.4 ± 2.3 points. There were no correlations between training load variables (weekly training load, monotony, ACWR, and HRV), and recuperation subjective variables (well-being, fatigue, sleep, pain, stress, and mood). This case study showed that the training load can be varied in accordance with preparation for a specific competition and ACWR revealed that 50% of the training weeks were outside of the 'safe zone', however, no injuries were reported by the athlete. The effectiveness and cost of these methods are very practical during real world functional-fitness.
本案例研究的目的是量化一名女性精英运动员在进行38周功能性健身训练后的内部负荷量、急性/慢性工作量比率（ACWR）、幸福感认知以及心率变异性（HRV）。内部负荷通过训练课主观用力感觉评分（session-RPE）获得，而ACWR则通过将急性工作量除以慢性工作量（四周平均值）来计算。此外，每天早晨醒来后，在仰卧位时通过一款商用智能手机（HRV4training）对HRV进行测量。内部负荷量为：38周期间的每周平均总量为2092±861任意单位（AU）；2018年公开赛准备期间为1973±711 AU；2018年公开赛期间为1686±412 AU；地区赛准备期间为3174±595 AU。平均ACWR为1.1±0.5，且50%的周数超出了“安全区”。38周训练期间的幸福感评分为19.4±2.3分。训练负荷变量（每周训练负荷、单调性、ACWR和HRV）与恢复主观变量（幸福感、疲劳、睡眠、疼痛、压力和情绪）之间没有相关性。本案例研究表明，训练负荷可根据特定比赛的准备情况进行调整，ACWR显示50%的训练周数超出了“安全区”，然而，该运动员未报告有受伤情况。在实际的功能性健身中，这些方法的有效性和成本非常实用。
